LEO HIRSCHFELD, OF NEW YORK, .N. Y.

ROLLING-MACHINE.

To all whom it may concern:

Be it known that I, LEO HIRSGHFELD, a citizen of the United States, and a resident of the city, county, and State of New York, have invented certain Improvements in Rolling-Machines, of which the following is a specification.

This invention relates to certain improvements in that class of machines which are particularly designed and adapted for use in rolling plastic materials, such as candy, for example, and the object of the invention is to provide a machine of this general character of a simple and comparatively inexpensive nature, and of a compact and strong construction, which shall permit of being conveniently and rapidly operated for rolling plastic materials in a uniform and regular manner, without necessitating any special skill or experience upon the part of the attendant.

The invention consists in certain novel features of the construction, and combinations and arrangements of the several parts of the improved rolling machine, whereby certain important advantages are attained, and the machine is rendered simpler, less expensive and otherwise better adapted and more convenient for use, all as will be hereinafter fully set forth.

The novel features of the invention will be carefully defined in the claims.

In order that my improvements may be the better understood, I will now'proceed to Y describe the same with reference to the accompanying drawings, wherein Figure l is a side elevation of the machine with its operative parts adjusted in position to receive the candy or other ma;

terial to be rolled; Fig. 2 is a fragmentary elevation of the side of the machine opposite to that shown in Fig. 1; Fig. 3 is a partial plan view of the machine; Fig. 4 is a vertical section taken through the operative parts of the machine, showing the same as they appear during the rolling operation; Fig. 5 is a sectional View similar to Fig. 4,

but showing the operative parts of the machine in the positions in which they stand at the termination of the rollin operation; Fig. 6 is a fragmentary sectiona view showing the anti-friction bearing for the end of the adjustable rolling member of the machine; Fig. 7 is a fragmentary detail view showing one of the arms of the yoke for sup- Specification of Letters Patent.

porting said adjustable rolling member; Fig. 8- is a detached detail view showing a modified formation of the adjustable rolling member of the machine, and Fig. 9 is a view similar to Fig. 6, but showing another modified formation of the adjustable rolling member.

Referring first to Figs. 1 to 7, inclusive, the improved rolling machine, as therein illustrated, comprises a base frame 1 of any desired construction, having spaced inclined bars or supports 2, 2, extended in alinement along the opposite sides of its upper part and provided with upturned oppositely arranged bearing pieces 3, 3, wherein is journaled a driving shaft 4, extended horizontally across the frame, and provided at one end with a driving pulley 5, adapted for the passage of a belt or band 6, in order that the shaft may be driven from any suitable source of power during the operation of the machine.

At the side of the machine opposite to the driving pulley 5, the shaft 4 carries a sprocket wheel 7, around which is passed a sprocket chain or link belt 8, said chain also passing around a sprocket wheel 9 secured upon the adjacent end of a shaft 10, which is also journaled in the bearing pieces 3, 3,-

"to stand at an elevation above and at one side of said. shaft 4.

The spaced parallel shafts 4 and 10 are driven in unison and at the same speed, and carry between the bearing pieces 3, 3, drums or cylindrical members 11 and 12, of substantially equal diameters, with perimeters arranged in close proximity to each other, and affording, adjacent to the bight of said drums or members, a depressed receptacle adapted for the effective support of the candy or other plastic material placed in the machine. The perimetral surfaces of said drums or members 11 and 12 are longitudinally fluted or ribbed, as shown at 14 upon the drawings, so as to permit said surfaces to have effective contact with the candy supported upon them in order that continuous rolling movement may be imparted to such candy during the operation of the machine without liability of such candy adhering to said drums or members and being drawn down within the bight between them. In connection with the driven rolling members or drums l1 and 12, which are driven in the same direction by means of the sprocket gearing between the shafts 4 and 10, I also provide an auxiliary rolling member 15, which is made in the form of a roll or drum of considerably less diameter than the drums or members 11 and 12, and has conical or tapered ends which are supported for free rotatory movement in roller bearings 16, 16 produced at the upper ends of yoke arms 17, 17, which are tied or connected together at their upper ends back of the auxiliary rolling member 15 by means of a transverse brace or tie bar 18 and which have their lower ends secured upon a transverse shaft 19 extended across the frame members 2, 2 below the lower drum or member 11, and having its extremities mounted to rock in bearings as clearly shown in Figs. 1, 4 and 5 so as to permit said auxiliary rolling member to be moved toward and from the bight of the members 4 and'll when said shaft 19 and yoke arms 17 are rocked, as will be hereinafter ex plained. The shaft 19 carries an opening arm 20 the lower end of which has connection with one end of a spring 21 the opposite end of which is secured to the frame in such a way that the tension of said spring is exerted to rock the shaft in one direction and hold the yoke arms and the auxiliary rolling member 15 supported thereby normally separated from the bight of the members 4 and 11, as clearly shown in Figs. 1 and 2 of the drawings.

25, 25 represent bearing arms extended substantially at right angles from the frame members 2, 2 at the lower ends of the bearing pieces 3, 3, and said arms afford bearings at their outer ends for the extremities of a transverse shaft 26 which is extended across the machine outside the yoke arms 17 and is provided at its extremities with upwardly directed arms 27, 27 fixed upon it and connected at their upper ends by a transverse handle bar 28, adapted to be grasped by the hand of the attendant for imparting pivotal or rocking movement to said shaft 26. The.

shaft 26 is provided adjacent to its opposite ends with cams or eccentrics 30, 30, which are adapted for contact upon the upper surfaces of the yoke arms 17, in such a manner that when the shaft is rocked or turned in its bearings, said yoke arms are pressed downwardly from the position shown in Fig. 1 to that shown in Figs. 4 and 5, whereby the auxiliary rolling member 15 sup ported. by said yoke arms is pressed toward and from the bight of the members 4 and 11.

29, 29 represent sto s erected upon the bearing arms 25,25 an adapted for contact with the arms 27 when the handle bar is re tracted, during which movement the spring 21 exertsits tension to automatically raise the auxiliary rolling member 15 out of the bight oil. the members 4 and 11.

31, 31 represent screws carried upon the upper ends of arms 32, 32 projecting above the upper ends of the bearing pieces 8, 3 and adapted to be locked in adjusted position by means of lock-nuts 38, as clearly shown in Figs. 1 and 2, and these screws afford ad justablc stops to limit the swinging movement of the handle bar 28 away from the stops 29, whereby it will be understood that the extent of movement of the shaft 26, yoke arms 17 and of the auxiliary rolling member 15 may be conveniently regulated so as to insure accurate positioning of said auxiliary member 15 at each operation of the machine.

33, 33 represent levers pivoted at opposite sides of the upper ends of the bearing members 3, 3, as shown at 34 on the drawings, and the lower ends of these levers support an ejector rod or member 37, which is extended across the machine within the bight of the members 4 and 11, being normally held in lowered position closely adjacent to the perimeter of said members as indicated in Figs. 4 and 5 by means of springs 35. The upper ends of the levers 33, 33 are connected together by means of a transverse handle bar 39 which is extended horizontally across the upper part of the frame and is adapted to be grasped by the operator and forced downwardly to rock the levers 33 and elevate the ejector member 37 in such a manner as to insure the discharge of the candy from the machine after the same has been rolled.

40 represents a table supported upon the frame of the machine with its upper end closely adjacent to the perimeter of the lower member 11, said table being extended thence downwardly in an inclined direction so as to permit the candy to roll freely down its surface after being discharged from the bight of the members 4 and 11, and to be received, if desired, in a suitable receptacle arranged below said table.

The auxiliary rolling member 15, as clearly shown in Fig. 3 of the drawings, is provided with circumferential grooves or flutings which are extended in directions at right angles to the flutings of the members 4 and 11, and are adapted for contact with the candy to be rolled, being provided with opposite beveled surface, as clearly shown in said figure, so that when the said member is pressed upon the candy said oppositely beveled surfaces of the fiutings will operate to press thecandy in the direction of the length of said member 15, and in the operation of the improved machine the handle bar 28 being raised against its stops 29, and the yoke arms being elevated by the spring 21 so that the auxiliary member 15 is raised from the bight of the members 4 and 11, a piece of candy of proper size is inserted in the machine, being rested in the depressed receptacle afforded at the bight of the members 4 and 11 as indicated in Fig. 4 of the drawing, after which the handle bar 28 is grasped by the operator and moved in the direction indicated by the arrows at a" in Figs. 1 and 4, whereby the auxiliary member 15 is caused to press upon the candy opposite to the surfaces of the members 4 and 11, with which the candy is in contact. The rotatory movement of the driven members 4 and 11 will thereupon be imparted to the candy pressed in contact therewith so that said candy will likewise be rotated, and since the auxiliary member 15 is capable of free movement in its bearings 16, 1.6 it is evident that the rotatory movement of the candy will also be imparted to said auxiliary member 15 so that the surface of the candy will be smoothly rolled and formed into a cylindrical shape. As the movement of the handle bar 28 in the direction of the arrow 50 continues, the pressure exerted by the auxiliary member 15 upon the candy will serve to gradually reduce the diameter thereof until the desired diameter for the roll is attained, whereupon, as shown in Fig. 5, the ends of the handle bar will contact with the stop screws 31, 31 so that further movement of the handle bar and member 15 is effectively prevented, and the candy being then properly rolled, said handle bar 28 is released by the operator so that the spring 21 is permitted to exert its tension to raise the auxiliary member 15 and retract the handle bar to its initial position as shown in Fig. 1. The completed candy roll thereafter rests in rolling contact with the fluted perimeters of the members 4 and 11 until such time as the operator depresses the bar 39 to rock the levers 33, 33 and elevate the eject-or member 37 beneath the completed roll, whereupon by reason of the inclined positions of the members 4 and 11, the candy roll is carried up over'the upper perimetral sur face of the lowermost member 11 and is thereafter discharged by the rotation of said roll upon the table 40, and is permitted to roll down the same out of the machine, leaving the parts in position to receive a fresh piece of candy to be rolled.

From the above description of my invention it will be seen that the improved rolling machine constructed according thereto is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and rapidity of its operation and of the accuracy with which the candy is rolled during the use of the machine, and it will also be obvious from the above description of my invention that the machine constructed ac cording thereto is capable of considerable set forth in carrying out my invention in practice. For example in Fig. 8, I have shown a modified formation of the adjustable auxiliary rolling member 15 wherein the fiutings thereof, instead of being each provided with two oppositely beveled faces are each provided with but one such beveled surface, the flutings at one end of the member having their bevels directed in one way so as to press the candy toward that end of the member, while the flutings at the opposite end of said member are reversely beveled so as to press the candy in the reverse direction. Simllarly in Fig. 9 the perimeter of the member 15 is provided with reverse spiral flutmgs at its opposite ends, the flutings at one end being adapted to press the candy in one direction whilethose at the opposite end are adapted to press the candy in the opposite direction.
